A moving primary source sheds light on the experience of Japanese American children imprisoned in a World War II internment camp. A classroom diary created by Japanese American children paints a vivid picture of daily life in a so-called "internment camp." Mae Yanagi was eight years old when she started school at Topaz Camp in Utah. She and her third-grade classmates began keeping an illustrated diary, full of details about schoolwork, sports, pets, holidays, and health—as experienced from behind barbed wire. Diary pages, archival photographs, and narrative nonfiction text convey the harsh changes experienced by the children, as well as their remarkable resilience.
